BUTTLER, P.J.

The trial court found that defendant suffers from a mental disorder, is dangerous to himself and to others and that he is unwilling, unable or unlikely to participate in treatment on a voluntary basis, and ordered him committed. ORS 426.070 et seq. The court then ordered that defendant be prohibited from purchasing or possessing firearms for a period of five years, pursuant to ORS 426.130(1)(b)(D). On appeal, defendant challenges only the order prohibiting him from purchasing or possessing firearms.

On the night that defendant was taken to the hospital by Deputy Gates, he had threatened to kill Margaret Zamora's husband, Tony. Defendant had come "into the kitchen with [an] ax kind of behind his back" and took the ax into Zamora's back yard. He was very hostile. Defendant said, "Well, I have to do it tonight. I have to finish the job tonight. I didn't do it New Years' Eve so I've got to get it done tonight." When Zamora asked him what he was going to get done, defendant said, "I've got to kill." When Zamora asked whom he wanted to kill, defendant said, "Bob [his ex-wife's by then deceased husband] and Tony." When Gates arrived at Zamora's home, defendant lunged at the officer, going for his gun.

Defendant drinks heavily and, when he drinks, he becomes hostile and aggressive. He had taken overt steps toward killing his ex-wife's second husband, Bob Socha. He had planned to take him to the country in Socha's car and kill him. He deliberately broke the inside door handle on the car so that Socha would be unable to get out. As it turned out, however, Socha was murdered by defendant's roommate, Pitts (who also was Socha's brother-in-law). Defendant was pleased that Socha had been killed but wished that he, rather than Pitts, had done the killing.

ORS 426.130 provides, in relevant part:

"(1) After hearing all of the evidence, and reviewing the findings of the examining persons, the court shall determine whether the person is mentally ill. If, in the opinion of the court, the person is:

"* * * * *

"(b) Mentally ill based upon clear and convincing evidence, the court:

"* * * * *

"(D) Shall order that the person be prohibited from purchasing or possessing a firearm if, in the opinion of the court, the prohibition is necessary as a result of the person's mental or psychological state as demonstrated by a past pattern of behavior or participation in incidents involving unlawful violence or threats of unlawful violence, or by reason of a single incident of extreme, violent, unlawful conduct." (Emphasis supplied.)

Defendant argues that ORS 426.130(1)(b)(D) violates his right to free speech under the state and federal constitutions, because it conditions his civil rights on communications of expressive behavior. He did not preserve either claim below, and we decline to consider them for the first time on appeal.

Defendant's main contention is that ORS 426. 130(1)(b)(D) violates his right to bear arms under the Oregon and federal constitutions. The right to bear arms is not absolute. In the exercise of its police power, the legislature may enact reasonable regulations limiting the right and has done so, for example, by prohibiting: possession of a firearm by convicted felons, ORS 166.270; State v. Robinson, 217 Or. 612, 618-19, 343 P.2d 886 (1959); carrying a concealed weapon, ORS 166.240; possession by inmates of institutions, ORS 166.275, and possession of loaded firearms in a public building. ORS 166.370. Limitation on the right to bear arms is permissible when the unrestricted exercise of the right poses a threat to the public and the means chosen to protect the public does not unreasonably interfere with that right. State v. Boyce, 61 Or. App. 662, 666, 658 P.2d 577, rev den 295 Or. 122 (1983).

Given the nature of firearms, see State v. Kessler, 289 Or. 359, 369-70, 614 P.2d 94 (1980), the danger that the statute seeks to avert here is a serious one. The restriction on the right of mentally ill persons to bear arms, on the other hand, is relatively minor. The statute is narrowly drawn and may be invoked only when it is shown that the prohibition is necessary "as a result of the mentally ill person's mental or psychological state," as demonstrated by past behavior that involves unlawful violence or threats of unlawful violence. Although the statute imposes no time limit on the prohibition, ORS 166.274(6) permits the person to obtain judicial relief from an order under ORS 426.130(1)(b)(D). Because the regulation is a reasonable and narrowly drawn restriction on the right to bear arms, it does not violate Article I, section 27. State v. Robinson, 217 Or. 612, 343 P.2d 886 (1959).

Defendant next contends that the statute requires proof by clear and convincing evidence to support an order restricting his right to bear arms and that the trial court did not use those words. ORS 426.130(1)(b) requires that the court first find by clear and convincing evidence that a person is mentally ill. The dispositional provisions that follow, of which ORS 426.130(1)(b)(D) is one, do not require that quantum of proof. However, if the court orders that the person be prohibited from purchasing or possessing a firearm, ORS 166.274(6) requires that, in order to regain that right, he must show by clear and convincing evidence that he poses no threat to public safety. We assume that the omission of a similar requirement to support the prohibition from purchasing or possessing a firearm is a deliberate legislative choice. See Donaldson v. Lane County Local Govt. Bdry. Comm., 99 Or. App. 430, 433-34, 782 P.2d 449 (1989). Even if that quantum of proof were required, on de novo review, we hold that there is clear and convincing evidence to support the order.

Defendant also argues that, if the statute requires less than clear and convincing evidence, it violates the federal Due Process Clause. Galioto v. Department of Treasury, 602 F. Supp. 682 (DNJ 1985), vacated 477 U.S. 556 (1986), held that a similar federal statute violated federal due process standards, because the defendant had no opportunity to regain his right by showing that he was no longer dangerous. The court held that the irrebuttable presumption that, once committed, the person was forever mentally ill and dangerous and permanently prohibited from possessing a firearm, violated due process, because it did not "include [a] provision for the granting of relief from [firearm] disability to former mental patients" and, therefore, was not rationally related to public safety. 602 F Supp at 691. The Oregon statutory scheme, however, permits a person who is subject to such an order to show that he no longer poses a threat to the safety of society and, thereby, regain his right to possess or purchase firearms. There is no violation of federal due process rights.

Finally, defendant contends that the statute is void for vagueness under Oregon Constitution, Article I, sections 20 and 21. The vagueness test applies only to criminal laws; accordingly, it is inapplicable here. Megdal v. Board of Dental Examiners, 288 Or. 293,299, 605 P.2d 273 (1980); Anderson v. Peden, 284 Or. 313, 324, 587 P.2d 59 (1978).

Affirmed.
